Dear Cor., I read your post and I am writing to encourage you.  You see my husband has had Chronic hives for over 12 years and has been on numerous medications that stop the hives, but do not get to the cause.  I write this to encourage you to keep doing what you are doing with your diet.  That is the key - the key is to kill the candida.
 
My husband finally about 6 months ago saw a naturopath that told him that the cause of the hives was the candida and the cure was in the diet. The same one you are on.   Also, it is important to take a good probiotic to replace the good flora - one that needs to be kept in the refrigerator.  Also, to take caprylic acid capsules to kill the bad flora (there are many different products that do this)  The books by Doug Kaufman explain this.  Your hives will probably get worse as the bad flora die off.
 
To encourage you I will say that after about 6 months my husbands hives have all gone away.  Praise God.  He was so miserable as you can truly understand.  But before the diet worked - he had hives all over from head to toe for a long time as the bad flora was dying off.  Very miserable.  But it is over after all those years.  So keep up the diet - that is the key.  No sugar, grains, yeast, vinegar, etc.  They feed the yeast.
 
Also, prayer is so important as you have requested.  I pray you will be totally healed and that you will have the strength to withstand the hives until your healing is manifested.  Don't give up.  Don't cheat on the diet.
 
By the way, my husbands hives were due to food allergies that developed from the candida.  He was allergic to all salicylate containing foods, sulpher containing foods, msg, red dye, mold (cheeses), aspirin - if he ate any of those products he broke out in hives.
 
God bless you with healing.  MJ
